seems i did this in the worst possible way. entered markarth thru A Night to Remember, but i did see the Margeret attack (killed the guy before he killed her). read Etrys' note but instead of going to meet him, i explored the city, and pickpocketed the journals off everybody. Marg, Thonar, Nepos. so now when i go into Tloas, the guards have already killed Etrys and want to take me to jail. i've left off there because i found out how much other stuff there was to do for this, like finding evidence. can i restart this using setstage commands? one of the wikis states setstage doesn't work, but wanted to ask here first.

any advice appreciated! thanks
